An eligible advanced biofuel producer who receives payments under this subpart may be required to refund such payments as specified in this section. If the Agency suspects fraudulent representation through its site visits and records inspections under § 4288.105(b), it will be referred to the Office of Inspector General for appropriate action.

(a) An eligible advanced biofuel producer receiving payments under this subpart shall become ineligible if the Agency determines the advanced biofuel producer has:

(1) Made any fraudulent representation; or

(2) Misrepresented any material fact affecting a Program determination.

(b) If an Agency determination that a producer is not eligible for participation under this subpart is appealed and overturned, the Agency will make appropriate and applicable payments to the producer from Program funds, to the extent such funds are available, that remain from the fiscal year in which the original adverse Agency decision was made.

(c) All payments made to an entity determined by the Agency to be ineligible shall be refunded to the Agency with interest and other such sums as may become due, including, but not limited to, any interest, penalties, and administrative costs as determined appropriate under 31 CFR 901.9.

(d) When a refund is due, it shall be paid promptly. If a refund is not made promptly, the Agency may use all remedies available to it, including Treasury offset under the Debt Collection Improvement Act of 1996, financial judgment against the producer, and referral to the Department of Justice.

(e) Late payment interest shall be assessed on each refund in accordance with the provisions and rates as established by the United States Treasury.

(1) Interest charged by the Agency under this subpart shall be established by the United States Treasury. Such interest shall accrue from the date such payments were made by the Agency to the date of repayment by the producer.

(2) The Agency may waive the accrual of interest or damages if the Agency determines that the cause of the erroneous payment was not due to any action of the advanced biofuel producer.

(f) Any advanced biofuel producer or person engaged in an act prohibited by this section and any advanced biofuel producer or person receiving payment under this subpart shall be jointly and severally liable for any refund due under this subpart and for related charges.
